Threat Removed?

From TimesOnline:
"Iraq May 01, 2003

We have removed threat to America, Bush will announce
From Roland Watson in Washington and Richard Beeston in Baghdad

PRESIDENT BUSH will fly hundreds of miles out to sea today to claim from the flight deck of a US aircraft carrier the success of allied combat in Iraq."

To what threat does Bush refer? Anything removed from Iraq so far was no threat. Anything he claimed was a threat (e.g. WMD) they haven't found, so what does he mean?
